Robert Kennedy's Home Water Fluoridation System

Water Fluoridation

Water fluoridation
is the process of increasing the concentration of fluoride ions
in drinking water to reduce the incidence of tooth decay.
Dentists and public health experts find it very helpful
for reducing tooth decay.
Fluoride ions in drinking water
partially convert apatite to fluoroapatite in tooth enamel,
making it more resistant to acids produced by bacteria.

Below is a picture of the fluoridator and
my transcription of the explanatory placard.
This is only marginally connected to the theme of these pages,
but it's my call.
It's unusual plumbing that I have seen,
plus a tie-in to amusingly nutty conspiracy theories.

This prototype apparatus to fluoridate a home water
supply was installed around 1960 in the home of
Attorney General Robert F. Kennedy in McLean, Virginia.
The Kennedy household was selected for the trial
because of the number of small children whose teeth
would benefit from fluoridated water. The devices was
found to be inefficient and difficult to maintain.

My cromwell-intl.com domain appeared in September, 2001,
although the Wayback Machine didn't notice its one enormous
Toilet of the World page until
January 17, 2002.
Some time soon after that I split it into categories,
and the collection has grown ever since.

In December, 2010 I registered the
toilet-guru.com
domain and moved the pages to a dedicated server.
